产物英文概述
IFN-alphas are proteins secreted by leukocyte. They are mainly involved in innate immune response against viral infection. The IFN-alpha family has 13 subtypes and 23 different variants. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.来历

生物活性
Fully biologically active when compared to standard. The activity is determined by the cytopathic effect inhibition assay.表面
Sterile Filtered White lyophilized (freeze-dried) powder.配方
Lyophilized from a 0.2 um filtered solution in PBS, pH 7.4, with 0.02 % Tween-20.内毒素
Less than 0.1 EU/ug of rHuIFN-alpha2c, Yeast as determined by LAL method.消融申明
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.贮存前提
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.参考材料
